There might be two issues here. First off, if your python scripts have the .pyw extension then they will be associated with pythonw which does not use a console*. However, you have shell=True, which generates a console*. You need to run the program and hide the console:
*Pedantically, it's not a dos prompt, it is a console window. DOS - Disk Operating System - was an IBM mainframe OS. MS-DOS or PC-DOS command-line features were mirrored (with a lot of extra features) by cmd.exe (a Windows shell), which is a console program and so uses a console window. It's that console window you need to hide.

You need to use
startupinfo parameter of subprocess.Popen() class' constructor.
You do not need
shell=True if all you want is to hide console window; see this answer.

The newer
subprocess.check_output and similar commands are supposed to replace os.system . See this page for details. While I can't test this on Windows, the following should work:
check_output returns a string of the output from your command. Parallels desktop 10 for mac cracked. Alternatively, subprocess.call just runs the command and returns the status of the command (usually 0 if everything is okay).
Cant find app under apllication mac. Also note that, in python 3, that string output is now
bytes output. If you want to change this into a string, you need something like
If necessary, you can tell it the kind of encoding your program outputs. The default is MikeMike
utf-8 , which typically works fine, but other standard options are here.

You would use the os module system method.
You just put in the string form of the command, the return value is the windows enrivonment variable COMSPEC
For example:
os.system('python') opens up the windows command prompt and runs the python interpreter
